The full extent of the CIA's extraordinary rendition programme has been laid bare with the publication of a report showing there is evidence that more than a quarter of the world's governments covertly offered support.

A 213-page report compiled by the Open Society Justice Initiative (OSJI), a New York-based human rights organisation, says that at least 54 countries co-operated with the global kidnap, detention and torture operation that was mounted after 9/11, many of them in Europe.

So widespread and extensive was the participation of governments across the world that it is now clear the CIA could not have operated its programme without their support, according to the OSJI.

"There is no doubt that high-ranking Bush administration officials bear responsibility for authorising human rights violations associated with secret detention and extraordinary rendition, and the impunity that they have enjoyed to date remains a matter of significant concern," the report says.
